Human anatomy, including structure and development and practical considerations . 1126 A.\.\ opposite side which ciescenci within the tci,Miicntum, lateral and ventral to theposterior longitudinal fasciculus ; (3) tibrcs which cross to join the fasciculus retro-rtexus ; (4j fibres from the median fillet and (5) from the superior cerebellarpeduncle which traverse the cjjmmissure to reach the opposite thalamus; (6) per-haps fibres from the deeper gray stratum of the corjjora quadrigemina to the cerebralcortex of the other side. Its presence in all vertebrates and the very earlyacquisition of a medullary coat by its fibres indicate, as pointed out by Edinger,the fundainciital character of the commissure.

The lateral geniculate bodies, (corpora «ciiiculata latcraks), one on each side,are two fusiform elevations, about 10 mm. in length and half as much in width, whichproject from the outer and under surface of the posterior part of the thalamus (). They are so buried within the thalamus that they are much less distinct
